1 Heat transfer film is a commonly used printing material, widely used in various products due to its convenient and fast printing method. However, during use, we often encounter some problems that affect the heat transfer printing effect. This article will explore several common issues with heat transfer film and provide corresponding solutions.
2、 Common issues with heat transfer film
1. Uneven film surface
The unevenness of the film surface may be due to quality issues with the heat transfer film itself, or improper temperature and pressure control during the heat transfer process. An uneven film surface can reduce the clarity of printed patterns and affect the aesthetics of the product.
2. Color distortion
Color distortion may be due to inaccurate color matching of the heat transfer film, or excessive temperature during the heat transfer process, resulting in color changes. Color distortion can seriously affect the visual effect of the product.
3. Blurred pattern
Pattern blurring is usually caused by insufficient resolution of the heat transfer film, or improper control of parameters such as pressure, temperature, and time during the heat transfer process, resulting in a decrease in the clarity of the printed pattern.
4. Insufficient adhesive force
Insufficient adhesion may be due to poor adhesive quality of the heat transfer film, or improper temperature and pressure control during the heat transfer process, resulting in insufficient melting of the adhesive and affecting the adhesion.
5. Membrane deformation
The deformation of the film material is usually caused by excessive temperature or pressure during the heat transfer printing process, resulting in deformation of the film material. The deformation of the film material can seriously affect the aesthetics of the product.
6. Bubble generation
The generation of bubbles may be due to the incomplete discharge of air between the heat transfer film and the substrate surface, or the high temperature during the heat transfer process causing the film material to shrink, trapping air between the film and substrate.
7. Poor durability
Poor durability may be due to poor material quality of the heat transfer film, or improper control of parameters such as temperature and pressure during the heat transfer process, resulting in a decrease in the durability of printed patterns.
8. High operational difficulty
The high difficulty of operation may be due to the complex use of heat transfer equipment or the lack of proficiency in the use of heat transfer film, resulting in an increased error rate during the operation process.
3、 Solution strategy
For uneven film surface, high-quality heat transfer film should be selected, and temperature, pressure and other parameters should be strictly controlled during the heat transfer process.
2. For color distortion, it is necessary to ensure accurate color matching of the heat transfer film and control the appropriate temperature during the heat transfer process.
3. For pattern blurring, a high-resolution heat transfer film should be selected, and parameters such as temperature, pressure, and time should be precisely controlled during the heat transfer process.
4. For insufficient adhesion, high-quality adhesives should be selected, and temperature, pressure, and other parameters should be strictly controlled during the heat transfer printing process.
5. For membrane deformation, appropriate heat transfer temperature and pressure should be controlled to avoid excessive or insufficient temperature and pressure causing membrane deformation.
6. For the generation of bubbles, it is necessary to ensure that the surface of the substrate is clean and dust-free before heat transfer printing, and to fully exhaust the air between the film material and the substrate during the heat transfer printing process.
7. For poor durability, a heat transfer film with good durability should be selected, and temperature, pressure, and other parameters should be strictly controlled during the heat transfer process.
8. For operations with high difficulty, one should be familiar with the usage skills of heat transfer equipment and master the operation methods of heat transfer film proficiently to reduce errors during the operation process.
